OF HIGHLAND PARK, MICHIGAN ,ANDPENOCH PROUTY, BOTH TRUCK AND Bus IDENTIFYING Lieiir Application led May 26, 1927. Serial No.' 194,402.

The object of the invention is to provide a simple, cheap, and yet effective construction of device for use on trucks or busses Where the municipal regulations require the display of a plurality of lights of distinguishing color; to provide a construction wherein the eect of a plural display is secured by the employment of a single light; and to provide a construction wherein the support of the light is such that it will be maintained intact, irrespective of the jars to which such devices are subjected. t

With this object in view the invention consists in a construction'and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, wherein: n l

Figure 1 is a front elevational view of the invention.

Figure 2 is a longitudinal horizontal sectional view on the plane indicated by the line 2-2 of Figure 1.

Figures 3 and 4 are transverse vertical sectional views on theplanes indicated by the lines 3-3 and 4-4 of Figure 1.

The casing or housing 10 is made preferably of plate metal of comparatively heavy `auge and comprises the two sections 10a and 10b, the former being formed to provide the rear wall 11 and the top and bottom walls 12 and 13, the flanges 14 being inturned from th'e top and bottom walls and serving as a means for securing the section 10b in place. rI he section 10b comprises the front wall 15 and end wall 16 and the means for securen nient of the two sections together consist of screws 17 passing through body holes in the front wall of the section 10b and threadingly engaging tappe-d holes in the flanges 14, lock washers 18 being interposed between the heads of the screws and the front wall 15 to prevent recession of the screws.

The top and back walls 12 and 11 extend beyond the ends of the front and bottom walls to provide attachment brackets 19 at either end of the casing, in which attachment brackets are formed fastener holes 20.

In the front wall 15 there are formed the openings 21 uniformly spaced along the front wall and directly behind the latter is the brackets. the brackets are Aprovidedy Vwith foot' or j base plate 37 secured in place by detachable a light penetrable panel 22 of the color prescribed 'by the regulations under which the device is used. The panel 22 is disposed behind the flanges 14 and ateach end is spanned by cushions 23 of felt or some other acceptable vmaterial which is interposed beof the'latter and serve as a means for the support of the mirrors 27 which are secured in place thereon by pliable lips 28 carried by In addition to the flanges 24,

flanges 29V resting upon the bottom wall 13- and secured to the latter by means ofV fasteners 30. The brackets, 26 vare disposed directly behind the end openings 21 in the front wall and behindv the center opening is disposed the illuminating medium in the form of a lamp 31 removably mounted in a socket 32 carried at the upper extremity of a coil spring 33, the latter being secured to va base plate 34 which is in turn secured to the bottom wall 13 of the casing by ineansof bolts or fasteners 35. v l

Inthe bottoni wall 13 of the casing is formed an opening 36 closed by a removable fasteners 38.

The spring 33 serves as a support for the lamp and is of a gauge of wire suliicient to maintain it normally upright andto support the weight of the lamp. It constitutes, however, a flexible support for the' lamp so that the latter is not likely to be damaged by jolting or jarring of the truck on which the device is used. When the lamp is lit, the light j rays shine directly through the center opening 21 and are reiected through the end openings by the mirrors 27 disposed directly behind those openings. Thus the effect vof nature.Y

three lights is secured with but the use of one.

Should access to the casing be necessary, it may be had by the removal of the plate` 37 which would'readily permit the replacement of a burnt out lamp'through the opening 36.

The whole device may be dismantled `by the g disengagement of the screws `17 and the bolts Y A25 which Will'permit the removal ofthe sec- Vtion 10b and also the removal of the light penetrable panel 22. The vmirror bracket may be dismantled if desi-red by the removalof the bolts 3() and similarly the lamp bracket may be dismantled by the removal of the bolts 35.

The invention having been described, what is claimed as new and useful is :V Y

1i. A devicefor the purpose indicated comjprisingja'casing'formed of sheet metal and consisting ofja duality vof sections of which `one comprises theback, tjop and bottom walls and tlie other `the front and end walls, the

"first said section at the longitudinal edges ofthe top and bottom walls being formed lwith inturned flanges, and fasteners extendingthroughthe front walland engaging said flanges tosecure the two sections together. A device Vfor the ,purpose indicated comprisi'ng a casing composed of two sections of vwhich oneisfformedwith back, top and bottom walls andinturned anges at the edges 'ef the top and bottom walls and the other composed of front and end walls, fasteners extending through the frontwall -of'the second section andy'engaging the flanges ofthe first section, a light penetra-ble panel disposed bhind Suid .flanges 'and members Spanning "said panel at its opposite extremities and provided withmeansf for securing them to the flanges ofV said top and bottom walls.

Y 3. A device for the purpose indicated comprising a casing having an opening formed in the front Wall thereof,anfilluminating mem` ,ber disposed lbehind said, opening, and a laterally yieldable and longitudinally eXpanl sible and compressible support for said member.

4. A device for the purpose indicated comprising a casing having an opening iformed `in the front wall thereof, an illuminating member disposed behind said opening, v and a flexible support for said member consisting of a helical spring securedat one end tothe member and anchored to the casing at said other end. v
